Here is Filament Spool adapter, This adapter is designed to help make smaller 600 or 500 Gram spools fit and work in Ams or similar filament loaders, This design I made for my Anycubic ace pro to allow 600gram flashforge spools to load and retract correctly. To assemble the design simply place the small spool onto one of the halves and screw until tight, I've also included a spool without the wings In case someone finds a need to only have the inside adapter, Print settings No supports needed, Nozzle size 0.4mm, Layer Height 0.2mm, Infill 15%, Wall Count 3, Print speed 200mms,
